The current surgical approach is mostly urethroscopic Holmium laser lithotripsy for lithotripsy: first, the patient needs to undergo hemi-anesthesia and take the lithotomy position, i.e., the legs are raised and separated by 90 degrees. Second, the external genitalia of the perineal area should be disinfected to a minimum of 15 cm. Third, connect the urethroscope and TV monitor, and connect the laser. Fourth, enter the urethroscope into the urethra under direct vision, and reach the stone site under the guidance of the TV monitor, and use the laser power of about 25w to smash the stone into pieces, and flush it out of the body by saline flushing. Fifthly, if the stone is checked to be free of residue and the surrounding mucosa is free of bleeding, the urinary catheter can be left in place, which requires continuous flushing. The patient is awake from anesthesia and can be sent back to the ward.
